Description:
Glycomark Blood Test
The Glycomark test measures the level of 1,5 Anhydroglucitol (1,5-AG) in the blood. 1,5-AG is a molecule which is structurally similar to glucose. Normally, 1,5-AG levels in the body are stable. When blood glucose levels are abnormally high, 1,5-AG is eliminated from the body along with excess glucose in the urine. Measuring the level of 1.5-AG in the blood can help to determine if a person is experiencing unusual fluctuations of their glucose levels.
Some people with Diabetes experience unusual spikes in their blood sugar throughout the day, especially after eating. For people without diabetes or people with diabetes who are able to keep their blood sugar levels stable, the Glycomark test will come back with a normal or high result. People experiencing spikes in their glucose levels will show lower than normal results which typically take 1-2 weeks to return to normal.
The Glycomark score is reflective of blood glucose levels over the past 1-2 weeks. Other common tests such as a Hemoglobin A1c may show normal results even if a person is experiencing fluctuations in their glucose levels since these levels average out over a longer period of time. Identifying if a person is experiencing abnormal fluctuations in their glucose levels can help a person and their doctor address the issue before it causes more serious health complications. This condition known as Glycemic Variability has been linked to increased risk of kidney disease, nerve damage, heart disease, stroke, dementia, and death.
The Glycomark test may be ordered with a Hemoglobin A1c test for more thorough testing. For additional Diabetes testing including the Fructosamine test, please see our Diabetes Category.
Turnaround for this test is typically 2-6 business days.
